[jira] [Created] (LUCENE-2988) trunk 'ant test' hangs
trunk 'ant test' hangs
----------------------
Key: LUCENE-2988
URL: https://issues.apache.org/jira/browse/LUCENE-2988
Project: Lucene - Java
Issue Type: Bug
Components: Tests
Environment: inspected so far on XP within Cygwin using IBM JDK 6
Reporter: Doron Cohen
Assignee: Doron Cohen
Fix For: 4.0
Running 'ant test' from trunk on XP in a Cygwin shell hangs, taking 100% CPU.
There was no progress in the console for a long time, so i stopped the program.
Before stopping it, created 5 consecutive thread dumps to see where the code is.
It is not clear what is going on - does not seem like a Lucene code I think but not sure.
Opening this issue to keep an eye on this - I will try with other JDKs to see if this is persistent.
Also, when first seeing this had local changes of two issue: LUCENE-2986 and LUCENE-2977 - I think the changes in these issues are related but will repeat the tests without these changes.

Doron Cohen updated LUCENE-2988:
--------------------------------
Attachment: 5-java-dumps.zip
Attached contains 5 consecutive java dumps taken when the tests were hanging - in the hope that comparing the thread states in the files would reveal the problem.

-------------------------------------
Thanks Robert for looking into this!
bq. it seems they are from the 'ant' jvm, not the forked process that actually runs the tests
Indeed, now I notice that too... when 'ant test' hanged I used <CTRL BREAK> to get the thread dump and did not realize the ant JVM stands in between... That console is lost and I don't know the exact location in the tests when that happened - too bad.
bq. It could be the case here that its just in some ultra-slow test such as TestIndexWriterOnDiskFull... this one frequently takes several minutes for me even on Sun JRE.
I was away for half an hour so its something slower...
I was not able to reproduce this, and also in the meantime found out that I was using incompatible ant version - 1.8.1.
So thinking of closing this for now, will reopen it if it will reappear with ant 1.7.1.

-------------------------------------
I havent tried the tests with IBM's JRE in a while, I just did so and actually noticed some test failures. So it seems we have some issues to cleanup here.
As far as hangs, I inspected your dump files and it seems they are from the 'ant' jvm, not the forked process that actually runs the tests?
It could be the case here that its just in some ultra-slow test such as TestIndexWriterOnDiskFull... this one frequently takes several minutes for me even on Sun JRE.

Updated the description - removed the part about 100% CPU - apparently the CPU consumption was unrelated (though the tests do hang).
